2023-11-09riscv: Optimize bitops with Zbb extensionXiao Wang2-4/+252
This patch leverages the alternative mechanism to dynamically optimize bitops (including __ffs, __fls, ffs, fls) with Zbb instructions. When Zbb ext is not supported by the runtime CPU, legacy implementation is used. If Zbb is supported, then the optimized variants will be selected via alternative patching. The legacy bitops support is taken from the generic C implementation as fallback. If the parameter is a build-time constant, we leverage compiler builtin to calculate the result directly, this approach is inspired by x86 bitops implementation. EFI stub runs before the kernel, so alternative mechanism should not be used there, this patch introduces a macro NO_ALTERNATIVE for this purpose.

2023-11-09OSS: dmasound/paula: Convert to platform remove callback returning voidUwe Kleine-König1-4/+3
The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new(), which already returns void. Eventually after all drivers are converted, .remove_new() will be renamed to .remove(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

2023-11-09cifs: reconnect work should have reference on server structShyam Prasad N2-16/+34
The delayed work for reconnect takes server struct as a parameter. But it does so without holding a ref to it. Normally, this may not show a problem as the reconnect work is only cancelled on umount. However, since we now plan to support scaling down of channels, and the scale down can happen from reconnect work itself, we need to fix it. This change takes a reference on the server struct before it is passed to the delayed work. And drops the reference in the delayed work itself. Or if the delayed work is successfully cancelled, by the process that cancels it. Signed-off-by: Shyam Prasad N <[email protected]> Signed-off-by: Steve French <[email protected]>
2023-11-09cifs: do not pass cifs_sb when trying to add channelsShyam Prasad N3-8/+8
The only reason why cifs_sb gets passed today to cifs_try_adding_channels is to pass the local_nls field for the new channels and binding session. However, the ses struct already has local_nls field that is setup during the first cifs_setup_session. So there is no need to pass cifs_sb. This change removes cifs_sb from the arg list for this and the functions that it calls and uses ses->local_nls instead.

This is not a scalable approach, and does not make a lot of attempt to distribute the connections.

Proposed patch fixes initialization of CSC3551 on the UM5302LA laptop. Patching DSDT table is not required since ASUS did added _DSD entry. Nothing new introduced but reused work started by Stefan B. Currently there is no official firmware available for 10431A83 on cirrus git unfortunately. For testing used 104317f3 (which is also seems on i2c bus): $ cd /lib/firmware/cirrus/ && \ for fw in $(find ./ -name '*104317f3*'); do newfw=$(echo $fw | sed 's/104317f3/10431a83/g'); echo echo "$fw -> $newfw"; ln -s $f $newfw; done With the patch applied to 6.6.0 and obviously symlinks to 104317F3 FW, speakers works and to my susrprise they sound quite good and loud without distortion. Probably confirmation from cirrus team is needed on firmware.

2023-11-09ALSA: info: Fix potential deadlock at disconnectionTakashi Iwai1-8/+13
As reported recently, ALSA core info helper may cause a deadlock at the forced device disconnection during the procfs operation. The proc_remove() (that is called from the snd_card_disconnect() helper) has a synchronization of the pending procfs accesses via wait_for_completion(). Meanwhile, ALSA procfs helper takes the global mutex_lock(&info_mutex) at both the proc_open callback and snd_card_info_disconnect() helper. Since the proc_open can't finish due to the mutex lock, wait_for_completion() never returns, either, hence it deadlocks. TASK#1 TASK#2 proc_reg_open() takes use_pde() snd_info_text_entry_open() snd_card_disconnect() snd_info_card_disconnect() takes mutex_lock(&info_mutex) proc_remove() wait_for_completion(unused_pde) ... waiting task#1 closes mutex_lock(&info_mutex) => DEADLOCK This patch is a workaround for avoiding the deadlock scenario above. The basic strategy is to move proc_remove() call outside the mutex lock. proc_remove() can work gracefully without extra locking, and it can delete the tree recursively alone. So, we call proc_remove() at snd_info_card_disconnection() at first, then delete the rest resources recursively within the info_mutex lock. After the change, the function snd_info_disconnect() doesn't do disconnection by itself any longer, but it merely clears the procfs pointer. So rename the function to snd_info_clear_entries() for avoiding confusion. The similar change is applied to snd_info_free_entry(), too. Since the proc_remove() is called only conditionally with the non-NULL entry->p, it's skipped after the snd_info_clear_entries() call.

2023-11-09btrfs: make OWNER_REF_KEY type value smallest among inline refsBoris Burkov1-8/+16
BTRFS_EXTENT_OWNER_REF_KEY is the type of simple quotas extent owner refs. This special inline ref goes in front of all other inline refs. In general, inline refs have a required sorted order s.t. type never decreases (among other requirements). This was recently reified into a tree-checker and fsck rule, which broke simple quotas. To be fair, though, in a sense, the new owner ref item had also violated that not yet fully enforced requirement. This fix brings the owner ref item into compliance with the requirement that inline ref type never decrease. btrfs/301 exercises this behavior and should pass again with this fix.

2023-11-09btrfs: fix qgroup record leaks when using simple quotasFilipe Manana2-3/+3
When using simple quotas we are not supposed to allocate qgroup records when adding delayed references. However we allocate them if either mode of quotas is enabled (the new simple one or the old one), but then we never free them because running the accounting, which frees the records, is only run when using the old quotas (at btrfs_qgroup_account_extents()), resulting in a memory leak of the records allocated when adding delayed references. Fix this by allocating the records only if the old quotas mode is enabled. Also fix btrfs_qgroup_trace_extent_nolock() to return 1 if the old quotas mode is not enabled - meaning the caller has to free the record.

2023-11-09btrfs: fix race between accounting qgroup extents and removing a qgroupFilipe Manana1-1/+7
When doing qgroup accounting for an extent, we take the spinlock fs_info->qgroup_lock and then add qgroups to the local list (iterator) named "qgroups". These qgroups are found in the fs_info->qgroup_tree rbtree. After we're done, we unlock fs_info->qgroup_lock and then call qgroup_iterator_nested_clean(), which will iterate over all the qgroups added to the local list "qgroups" and then delete them from the list. Deleting a qgroup from the list can however result in a use-after-free if a qgroup remove operation happens after we unlock fs_info->qgroup_lock and before or while we are at qgroup_iterator_nested_clean(). Fix this by calling qgroup_iterator_nested_clean() while still holding the lock fs_info->qgroup_lock - we don't need it under the 'out' label since before taking the lock the "qgroups" list is always empty. This guarantees safety because btrfs_remove_qgroup() takes that lock before removing a qgroup from the rbtree fs_info->qgroup_tree. This was reported by syzbot with the following stack traces: BUG: KASAN: slab-use-after-free in __list_del_entry_valid_or_report+0x2f/0x130 lib/list_debug.c:49 Read of size 8 at addr ffff888027e420b0

2023-11-08net/sched: act_ct: Always fill offloading tuple iifidxVlad Buslov3-15/+32
Referenced commit doesn't always set iifidx when offloading the flow to hardware. Fix the following cases: - nf_conn_act_ct_ext_fill() is called before extension is created with nf_conn_act_ct_ext_add() in tcf_ct_act(). This can cause rule offload with unspecified iifidx when connection is offloaded after only single original-direction packet has been processed by tc data path. Always fill the new nf_conn_act_ct_ext instance after creating it in nf_conn_act_ct_ext_add(). - Offloading of unidirectional UDP NEW connections is now supported, but ct flow iifidx field is not updated when connection is promoted to bidirectional which can result reply-direction iifidx to be zero when refreshing the connection. Fill in the extension and update flow iifidx before calling flow_offload_refresh().

2023-11-08gcc-plugins: randstruct: Only warn about true flexible arraysKees Cook1-10/+0
The randstruct GCC plugin tried to discover "fake" flexible arrays to issue warnings about them in randomized structs. In the future LSM overhead reduction series, it would be legal to have a randomized struct with a 1-element array, and this should _not_ be treated as a flexible array, especially since commit df8fc4e934c1 ("kbuild: Enable -fstrict-flex-arrays=3"). Disable the 0-sized and 1-element array discovery logic in the plugin, but keep the "true" flexible array check.
